To u\u017e se jen tak nezvl\u00e1dne. A jestli mi to nev\u011b\u0159\u00edte, zkuste si to sami. Neusp\u011bjete.Ale p\u0159i kovov\u00fdrob\u011b se n\u011bkdy n\u011bjak\u00e9 ty otvory vytv\u00e1\u0159et mus\u00ed. N\u011bkter\u00e9 v\u00fdrobky z kovu se bez otvor\u016f neobejdou.

Jenom s t\u00edm se n\u00e1m poda\u0159\u00ed v\u0161echno provrtat tak, jak to m\u00e1 b\u00fdt.

Proto\u017ee je to koruna ke korun\u011b, a r\u00e1zem by vybaven\u00ed d\u00edlny st\u00e1lo majlant. Tak\u017ee by bylo dob\u0159e, kdyby se na\u0161la i n\u011bjak\u00e1 o dost v\u00fdhodn\u011bj\u0161\u00ed nab\u00eddka.
